Definitions
- the present invention relates in general to turbines for converting wind into mechanical energy and more particularly to an omni-wind vertical axis turbine.
- an omni-wind vertical axis wind turbine which is used to generate electricity or to provide direct power to a mechanical device by means of a power takeoff.
- the simple and uncomplicated structure provides a self-starting wind turbine which utilizes an omni-wind self starting air foil of efficient and simplistic design with a rotor assembly.
- the design of the vane permits application for generating energy from either flow of wind or liquid.
- Center mounted on a vertical rotor, when facing the wind one half of the wind sail on one side of the rotor presents a generally concave configuration to capture impinging wind thrust with the other half on the other side of the rotor 180 degrees away presenting a generally concave configuration to provide minimal resistance.
- the disparate resistance to the wind causes the wind to react more strongly on one half of the apparatus than the other.
- the unequal reaction causes the apparatus to rotate about its vertical axis.
- the wind sail halves have identical concave and convex configurations.
- the apparatus has omni-wind characteristics in that regardless of the wind direction an adequate portion of a concave surface will be exposed to impinging wind.
- the subsequent rotation of the rotor assembly is transmitted by a rotor assembly to an electrical turbine.
- FIG. 1 is a perspective elevational view of the vertical axis wind turbine apparatus in accordance with the present invention
- FIG. 2 illustrates in a top view how the configuration of the vane of the turbine apparatus of the invention reacts to impinging wind
- FIG. 3 illustrates a cutaway view of the vane of the turbine apparatus taken along lines 3 - 3 as shown in FIG. 1 ;
- FIG. 4 illustrates a cutaway view of the vane of the turbine apparatus taken along lines 4 - 4 as shown in FIG. 3 ;
- FIG. 5 illustrates a cutaway view of the vane of the turbine apparatus taken along lines 5 - 5 as shown in FIG. 3 ;
- FIG. 6 illustrates an embodiment of the invention wherein it is be used to generate electrical power from liquid wave motion
- FIG. 7 illustrates how the embodiment of FIG. 6 reacts when exposed to impinging liquid.
- the wind sail of the invention is formed in a unitary, or one piece configuration, and is centrally mounted to a rotor shaft.
- the wind sail consists of two joined vanes having an integrally formed centralized channel portion there between for receiving the rotor shaft.
- the vanes are mounted one on each side of the channel portion in generally planar arrangement, that is, 180 degrees apart.
- the vanes are substantially identical with each having a smoothly arced generally concave surface with an opposite or reverse smoothly arced face that is generally convex.
- a first vane is oriented to present its concave face with the other vane oriented to present its convex face.
- the other vane is the same as the first vane but rotated 180 degrees vertically.
- shaft one vane presents its concave face to the wind while the vane 180 degrees away is oriented to present its reverse convex face to the wind.
- the concave face operates to capture the wind to force rotation of the rotor while the convex face offers minimal resistance to rotor rotation.
- the reverse, or backside, of the convex surface which is a concave face, is then presented to the wind, thus providing continued rotation of the rotor shaft.
- FIG. 1 is a perspective elevational view illustrating the vertical axis wind turbine apparatus, generally designated 10 , of the invention.
- apparatus 10 includes the unitary, or one-piece, generally vertically elongated wind sail 11 , rotor 12 , rotor bearing housing 16 , and turbine housing 13 .
- One-piece wind sail 11 includes generally identical vane portions 11 a and 11 b mounted onto rotor shaft 12 in folded over fashion as explained above.
- vane portion 11 a and 11 b are joined as one piece by means of an integral central channeled portion for receiving rotor shaft 12 , one vane portion on each side of the channeled portion.
- vane potions 11 a and 11 b merge as one piece in generally a straight line manner, that is 180 degrees apart, and at their junction point include a central channel portion for mounting onto rotor 12 .
- Vane portion 11 a and 11 b each have generally identical smoothly arced concave and a convex faces, and as shown mounted to rotor 12 vane 11 a has its concave face presented to the wind whereas vane 11 b is inversely mounted to present its convex face to the wind , that is, the same as vane 11 b but rotated vertically 180 degrees.
- the vane portions 11 a and 11 b of wind sail 11 are configured to simultaneously present a concave face 11 a and a convex face 11 b to impinging air, that is, wind sail 11 when facing the wind has portion 11 a configured to present its concave face to capture impinging wind thrust, as shown by the arrows, with the portion 11 b configured to present at the same time its convex face to thus provide minimal resistance to the wind thereby providing an imbalance of pressure about rotor 12 resulting in rotary motion of the sail 11 .
- vane 11 b begins to present its concave face to the wind and vane 11 a to present its convex face to the wind, thus to continue rotation of wind sail 11 .
- the concave vane portions include a ridged side edge as illustrated by edge 11 c and protruding top and bottom edges as illustrated by edges 11 e that are configured to provide increased concavity and thus additional wind capture means.
- the combination of simultaneously providing a concave face of a vane, as illustrated by 11 b on one side of the rotor 12 and a convex face, as illustrated by 11 b on the other side of the rotor operates to provide unequal wind pressure about rotor 12 to provide omni-wind characteristics to the apparatus 10 configuration, that is, regardless of the wind direction an adequate portion of a concave surface will become exposed to impinging wind.
- FIG. 2 in top view illustrates the configuration of the wind sail 10 of the invention and the manner in which it reacts to impinging wind.
- wind impinges and is captured on the concave vane portions 11 a of the wind sail 11 while sliding from the convex portions 11 b to produce rotation in a clockwise direction as illustrated by the arrow.
- the wind sail 10 is inversely mounted to the rotor 12 the impinging wind would rotate the wind sail 10 in the counter-clockwise direction. Since the portions 11 a and 11 b are essentially identical, but inversely oriented portion 11 a has a reverse side identical to portion 11 b and vice versa.
- each vane has a back side identical to the others front side resulting in one half of wind sails 11 always presenting a significant portion of a concave face to the wind in order to start and maintain rotation of the wind sail 11 and the other half presenting a corresponding convex face.
- the vanes are thus non-planar, being slightly arced in opposite directions with more curved, or abruptly ridged side ends, such that as the vane rotates the side capturing the wind comes in line with the direction of the wind and then transitions to become the non-resistant half and vice versa.
- the top view of wind sail 10 shows a reversed S-shaped configuration whereas if inversely mounted to rotate in the counter-clockwise direction the top view would present an S-shaped configuration.
- Top and bottom edges 11 e further contribute to the disparate resistance to the wind causing the wind to react more strongly on one half of the apparatus than the other. The unequal reaction, in turn, causes the apparatus to rotate about its vertical axis.
- edges 11 c , 11 d exacerbate the concavity and convexity to thereby, respectively, more effectively hold and release the wind.
- the subsequent rotation of the rotor shaft is transmitted by a rotor assembly to an electrical generator.
- vane blades 11 a and 11 b , are shown, it is understood that more identical blades could be mounted at selected angles from each other, such as for instance, three blades located 120 degrees apart.
- FIG. 3 is a cutaway view of the apparatus 10 , taken along lines 3 - 3 as indicated in FIG. 1 .
- Wind sail 11 is indicated as rectangular, although some other suitable configuration may be used in keeping with the invention, and is centrally mounted on the rotor 12 , having substantially identical portions 11 a and 11 b as previously described.
- Rotor 12 extends through rotor bearing housing 16 and coacts in any suitable manner with turbine 14 of turbine housing 13 , the rotor 12 rotated by operation of wind sail 11 to provide rotary motion for powering the turbine 14 .
- Turbine 14 in turn provides electric power to storage means 15 with the electric power accessed at power outlet 15 a . It is understood that the rotary power could as well be applied to an electrical motor or any other suitable device.
- FIG. 4 illustrates in cutaway view the vane 11 a of the invention, taken along lines 4 - 4 as shown in FIG. 3 , in which the relative configurations of ridged edge 11 c and top and bottom edges 11 e are more clearly shown. In this manner the rotational effect on wind sail 11 by impinging air is maximized.
- FIG. 5 illustrates in cutaway view the vane 11 a of the invention, taken along lines 5 - 5 as shown in FIG. 3 , in which the relative configurations of vane portion 11 a , side edge 11 c , and bottom edge 11 e are shown.
- the vane portion 11 a and 11 e clearly show the smoothly arced curved configurations of the concave and convex vane portion of the invention.
- FIG. 6 presents another embodiment of the invention illustrating the manner in which electrical power can be generated from continuous flow of a liquid such as water.
- a vane portion of the invention generally designated 60
- a rotor 63 a With only one portion, or blade, 60 a immersed, or partially immersed, in the water 62 .
- the motion of water 62 impinges blade 60 a the resulting turning of the rotor 63 a operates to generate power from the turbine 64 .
- the invention is shown supported by a simple arrangement although it is understood that any arrangement compatible with the environment of use could be employed.
- vanes are shown, it is understood that additional vanes could be used mounted on the rotor 63 at selected angles from each other. In fact, if axis 63 is located above the water 62 then a third blade (not shown) identical to blade 60 a would likely be required.
- FIG. 7 better illustrates in an end view the manner in which a vane of the invention reacts to impinging liquid. This is an instance where the axis 63 is above water and thus a third blade would be used if necessary.
